This error occurs due to a problem on the server, not in MyDirect. The *.frm files are MySQL table definition files. The problem is that the database contains incorrect data and may be corrupted. Please check the constraints consistency of your database

Well i am using MYSQL community server 6.0 and according to the steps mentioned in documentation i copy and paste data folder from server folder to embedded server folder. When i connect through server settings it works fine but with embedded database settings it shows the above message. well as far as concerned to the constraints and security issues theres no constraints and checks on the data yet.

I think that the problem may be in compatibility between different 6.0 versions of desktop and embedded MySql servers. Try to create test tables against the MyDirect connection from script, not by copying them from the desktop server folder. Than perform your SQL queries on those test tables. If the error is reproduced with this test script, please send it to us and we will deal with it.

The problem is in possible incompatibility of your desktop and embedded MySQL servers, espesially in the table definitions files.
To ensure that the problem is or is not caused by MyDirect please create test tables on your embedded server from the following test script and perform simple SQL statements.
If these statements proceed this would mean that MyDirect itself has no problems with your MySQL embedded server version. In this case you need to recreate your database on embedded server from your own script, not by copying table data directly from the desktop server to embedded server catalog.

I've sent you the script that creates two test tables to e-mail specified in your profile.

The MySqlScript component is intended to execute scripts written in MySQL-compatible dialect of SQL. MSSQL Scripts use Transact-SQL dialect of SQL.
Trasact-SQL differs from MySQL SQL in many ways, therefore you need to convert it to MySQL-compatible SQL yourself (manually or with the help of third-party tools) and than execute it with the MySqlScript component.
